To put my situation more into perspective, here are the tires I am considering.

They are 121 rated and 3197@65psi https://simpletire.com/paid?brand=ke...&delivery=Del3

I also wouldn’t mind the 305/70r17 because they aren’t much bigger than my 285s.

@Power247 How was the strain on your transmission?

I see you’ve got the Hemi currently.

I also believe I have 3.55 gears currently, and with my setup, mileage is decent, and overall satisfied.

I would like not to stress out the transmission too much.

That’s the overall goal.
My 2012 was the High Output 6.7 with 3.73 gears.

Overall I felt the larger size tires were actually easier on the truck.

It kept the RPMs in the sweet spot (1800-2000) when cruising at highway speed.

Remember thatDRD also tuned my truckD during this whole time, and I know his trans tuning helped alot too.
